Applicationled June' 23, 1923, Serial No. 647,363. Renewed August 14, 1925.

To all whom t may concern:

Re it known that I, Envmm)` BrsBiNo, a citizen of the United States, residing at Somerset, in the county of Somerset and State of Pennsylvania, have invented new and useful Improvements in Lock Nuts, of which the following is a specification.

This invention relates to nut locks, and contemplates the provision of a locking element designed for use in conjunction with a nut having a slot transversely across the face thereof, and a bolt having a flat portion, the locking element being associated. with the nutafter it has been tightened upon the bolt, the locking element being adapted to be bent to engage the both sides of the nutin a manner to prevent retrograde movement of the latter on the bolt.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a view showing the manner of locking the nut upon the bolt in accordance with the present invention.

Figure 2 is a sectional View on the line,

element.

As herein above stated, the invention is intended for use in conjunction with a bolt having a flat surface 11, and a nut 12 of the construction shown in Figure 4. This nut is of the usual design except that its face is providedk with transverse slots 13 which intersect the bore 14:. It will be noted that these slots also intersect each other, so that after the nut hasbeen tightened upon the bolt as much as possible, there is always one of these slots arranged transversely of the nut extending across the flat portion 11 of the bolt. This is necessary in order that the locking element to be herein after described can be associated with the nut to prevent retrograde movement thereof. If desired, the sides of the nut can be grooved as at 15 to accommodate the terminals of the locking elements when the latter are bent against the sides of the nut, but this is not absolutely essential, and the nut can be constructed with perfectly flat sides.

tightened upon the bolt, and obviously, the

extensions 18v are theny arranged to bear against the flat surfaces 1l between the latter and the threads of the nut 12. The outer extension 18 is then adapted to be bent against the face ofthe nut, while the lterminals of the body portions 16 and 17 of this i locking'element,` are adapted to be vbent against the adjacent sides of the nut, the body portions 16 and 17 being considerably longer than the width Vof the nut for this purpose. If the nut isrprovided ywith lthe grooves above `referred to, these terminals are bent in the grooves, which ofcourse makes the structure more etl'ectlve for the purpose intended, as the terminals cannot be very easily moved out of the grooves irrespective of the amount of strain to which the nut may be subjected.

While it is believed` that from the foregoing description, the nature and advantages of the invention will be readily ap'- parent, I desire tov have it understood that Ido not limit myself to what is herein shown and describedand that such' changes may be resorted to when desired as fall within the scopeof what is claimed.k

Having thusV described the invention, YI claim: n

In combination, a bolt having a atsurface, a nut adapted-to be threaded on the bolt and having transverse slots adapted to extend across the iiat'surface when the nut is tightened on the bolt, a locking element including a body portion adapted to be arranged in said slot withy its terminals projecting beyond the sides of the nut and 60 The locking element is clearly shown` in adapted to be bent against said sides, and and adapted to be bent across the latter for extensions projecting from said body porthe purpose specified.
